1. Report Industry Investment Rating - No specific industry investment rating is provided in the content 2. Core Viewpoints - The steel price will oscillate within a range due to insufficient fundamental contradictions [2] - The supply - demand pattern of glass and soda ash remains unchanged, and their prices will oscillate weakly [2] - The building material consumption data of ferrosilicon and silicomanganese is fair, and their alloy futures have rebounded [4] 3. Summary by Relevant Categories Glass and Soda Ash Market Analysis - Glass: The glass futures oscillated downward with active trading and decreased positions. Regionally, the spot market was weak and stable. This week, the inventory of float glass manufacturers was 59.442 million heavy cases, a 4.68% decrease from the previous week. Although the increase in cold - repair of glass production lines improved demand slightly, the supply contraction was insufficient, and the inventory, though decreasing, was still high. Glass factories need long - term losses to clear capacity [2] - Soda Ash: The soda ash futures oscillated downward. The spot price was stable, with mainly rigid demand purchases. The production, sales, and inventory data of soda ash all declined, slightly alleviating the supply - demand contradiction, but the inventory was still high. With the expected increase in cold - repair of float glass, the demand for heavy soda ash is challenged, suppressing the price [2] Strategy - Glass: Oscillation [3] - Soda Ash: Oscillation [3] Ferrosilicon and Silicomanganese Market Analysis - Silicomanganese: The building material consumption was strong and inventory reduction was fair. The silicomanganese futures rebounded following the black market. The spot market was strong. Due to continuous losses, the production and operating rate of enterprises continued to decline, but the reduction was insufficient, and the inventory reached a new high. Port manganese ore inventory increased slightly, and the total manganese element inventory was stable, providing cost support [4] - Ferrosilicon: The ferrosilicon futures rebounded following black commodities. The Hebei Iron and Steel Group entered the market for procurement, and the market was waiting for its price guidance. Currently, ferrosilicon has high production and inventory, and demand is weakening. As the loss - time of enterprises extends, the operating rate decreases, and the inventory declines, but the high inventory still suppresses the price [4] Strategy - Silicomanganese: Oscillation [5] - Ferrosilicon: Oscillation [5]
